Definition of C7 (cervical vertebra)

C7 (cervical vertebra): C7 is the symbol for the 7th cervical (neck) vertebral bone (C7) which is sometimes called the prominent vertebra due to the length of its spinous process (the projection off the back of the vertebral body).

The spinous process of the top thoracic vertebra (T1) just below C7 is sometimes even more prominent than that of the "prominent vertebra".
